Detailed Description

van Leer limiter: smooth, 2 ghosts, better order at extrema than Minmod.

Harmonic average of the differences: 2ab/(a+b) if same sign, 0 otherwise. No sign branch (no std::abs). Preferred over Minmod for preserving smooth growth modes (less dissipative at the density profile extrema).
